SOLDERING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 410,761, dated September 10, 1889.

Application filed May 10, 1889; Serial No. 310,335. (No model.)

in g the Ends of Square or Rectangular Shaped Metallic Cans, of which the following is a specification.

Our invention relates to an automatic solderinganachine in which an endless carrierchain moved by sprocket-wheels C and O and provided with hinged plates receives the cans to be operated on and carries them along with it through a trough of molten solder, at the same time revolving the cans over and over, thus bringing every side of the end of can in contact with the molten solder, and finally depositing them 011 end on a table or conveyer, out of contact with the machine, to cool off. lVe attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1' is a longitudinal section of the machine on line a". a; of Fig. Fig. 2 is a plan. Fig. 3 is a cross-section on line y y of Fig. 2, and Fig. 4 is an end View showing the tipping plate with its cam for removing the cans from the machine after being soldered.

Similar letters refer to si milar parts throughout the several views.

The machine consists of an iron framingA A, which is set on an angle or incline in the direction of its width. A trough a, which contains molten solder, runs along the low side of this frame, into which the can to be soldered dips. The outer side of this trough is higher than the inner side, forming a curb to prevent the can from slipping off the machine. This frame A A is designed to be set on the top of any well-known form of brickwork, in which will be built a gas-furnace for keeping the solder in the trough a in a liquid.

state, as is common in this class of machines. The two sides of frame A A are placed at a distance apart from each other, which will vary according to the length of cans to be operated on. This space between the sides of the frame is traversed in the direction of the arrow by the endless chain B. This chain is with it, as seen at d and (1 by a cam O for tripping it.

covered throughout its entire length with a series of double-hinged plates (1 (Pd (1 The lower one of each set of double plates is pivoted to the endless chain at points 1:, Fig. 1, and the upper plate of each set is pivoted to the lower one at the opposite side from the latters attachment to the endless chain, as shown att" in Fig. 1. The width of these double plates is about equal to the width of the space between the two sides of the frame A A. To the top plate of each set of double plates is rigidly attached on one side a toe or lifter K, which engages with a series of triplugs G, attached to one of the inner sides of the frame A at proper intervals. The lower plate of each set is cut out at 6 for the passage of the lifter K through it, so that the top plate may rise without moving the lower one. To the bottom plate of each set of double plates on one side (the opposite from that of topplate-lifter attachment) is rigidly attached a toe or lifter Z, which engages with a series of trip-lugs 0, attached to one side of frame A (the opposite from that to which the lugs G are attached) at proper intervals. NVhen the lifters l come in contact with trip-lugs e, the lower plate is raised, carrying the top plate A small space m is left between each set of double plates to allow the corner of the can to drop between them. This allows of a steadier support for the can and also brings the corner in better contact with the solder. A guide-plate h, Fig. 1, will be placed in the frame A A below the under side of endless chain B, for guiding the plates on their return motion and preventing them from opening out, so that they may be-in proper position to resume their work after passing the s procket-wheel 0'.

At the end of the machine (that at which the cans have arrived after being soldered) is a single hinged plate M, which is engaged This plate M is pivoted to the frame of the machine and works at right angles to the double plates on the endless chain B.

The operation of the machine is as follows: WVe will suppose that the endless chain, with its plates, is in such a position that none of the lifters Z nor K are in contact with. the trip lugs e and G. The plates will consequently be lying flat on the endless chain. A can being now placed, we will say, on the plates (1 and the machine started, it will travel along in the direction of the arrow until the lifter [of these plates (Z comes in contact with a trip-lug c. This will raise both the plates (1 and tilt the can over to a position like that shown byF, Fig. 1.. The plates (Z must lift high enough to throw the center of gravity of the can over from the plates (1 onto the'platc d at the same time that the lifter lot the plates (Z comes in contact with the trip lug e. The lifter K of the plates (1 comes in contact with trip-lug G, thereby raising the top plate of (1' simultaneously with the plates (1, and by thus doing forming a support for the can and preventing it from tumbling over. The motion of the machine continuing, both lifters Z and K will leave their respective trip-lugs e and G, and the plates d and top plate of cl will fall to the normal flat position. The cans center of gravity being on d, in falling with the plates it will come down on the plates (7 011 the side next adjacent to that which rested on the plates (Z. It will thus be seen that the can has been transferred from plates (Z to plates d,- having made one-quartcr of a revolution in its passage. The motion of the chain continuing, the lifter Zof plates (7 (which are carrying the can) comes in contact with another trip-lug e, which lifts both plates. At the same time the toe K of d? has engaged a trip-lug G, thus raising the top plate of (1 These plates in dropping transfer the can from plates (2 to plat-es (Z and cause it to make another quarter of a revolution. Thus the operation is continued. The can moving along with the endless chain and rolling over and over in its passage from one set of hinged plates to another, thereby brings all sides of one end of the can in contact with the solder in the trough (6. Upon the can arriving at the end of the machine the operation of soldering has been completed and the can is ready to be conveyed away from the machine. For this purpose the trip-lug e at this end of machine is made longer than the others. The lifters of plates coming in contact with this are kept up after the top plate of the pair in front of them has dropped. The can thereupon falls over and is pushed along by the plates in its rear onto the single hinged plate M, which is lying fiat on the plane of inclination of frame A A. After arrivin on the plate M the can is tilted over on its soldered end at right angles to the motion of the chain onto the table or convcyer N, higs. 2 and at.

Ilaving described the machine and its operation in the foregoing specification, we do claim as our invention, and desire to secure by Letters Patent, the following claims, viz:

1. A series of double-hinged plates pivoted to an endless chain and to each other, each plate having a lifting device secured to it, in combination with means for automatically actuating the lifting devices, substantially as herein described.

2. A series of double-hinged plates pivoted to an endless chain and to each other, each plate having a lifting device secured to it, in combination with the trip-lugs c and G, for automatically actuating the lifting devices, substantially as herein described.

The single pivoted plate M, adapted to move at right angles to the line of motion of the double plates on the endless chain, and a cam by which said single plate actuated, in' combination with said double plates pivoted to said chain and adapted to deliver the can from the machine,substantially as described.

t. In a can soldering machine, the combination, with an endless carrier for supporting the cans, of a pivoted plate adapted to move at right angles to the line of movement of the carrier and to receive the cans delivered therefrom, and means for actuating said single plate, substantially as described.
